Harmony
Develop powerful apps, secure blockchain transactions, and protect data with immutable ledger technology.
What is Harmony?
Harmony is a blockchain platform designed for building and deploying decentralised applications with a focus on security and data integrity. It provides developers with tools to create apps that use immutable ledger technology, ensuring transactions are secure and data records cannot be altered retroactively. The platform combines blockchain infrastructure with practical development features, making it accessible to teams building anything from financial services to supply chain tracking systems. Harmony operates on a freemium model, allowing developers to start building at no cost whilst offering premium features for production-scale applications. The platform appeals to developers, enterprises, and organisations that need verifiable, tamper-proof record keeping alongside the ability to build decentralised applications.

Write and execute self-executing contracts that automate agreements and transactions
Data protection
Cryptographic security ensures sensitive information stored on the ledger remains secure and unalterable
Developer tools and SDKs
APIs and libraries for multiple programming languages to simplify application development
Transaction security
Built-in mechanisms to verify and secure all transactions across the network
Freemium access
Start building without payment, with paid options for higher transaction volumes and priority support
Pros & Cons
Advantages
- Low barrier to entry with free tier access for development and testing
- Immutable record-keeping provides strong guarantees for data integrity and auditability
- Purpose-built for blockchain development, reducing complexity compared to building from scratch
- Suitable for use cases where transaction security and transparency are critical
Limitations
- Blockchain platforms typically have higher latency than centralised databases, which may not suit all applications
- Requires developers to understand blockchain concepts and smart contract programming to use effectively
- Transaction costs and network fees may accumulate at scale depending on the pricing model for the paid tier
Use Cases
Building decentralised finance (DeFi) applications with transparent, auditable transaction histories
Supply chain tracking systems where product provenance and movement must be verified and immutable
Healthcare records systems requiring secure, tamper-proof storage of sensitive patient data
Voting or governance systems needing transparent, verifiable record-keeping
Asset management platforms where ownership and transaction history must be permanently documented
